FLAX-HARVESTING ATTACHMENT.

To all whom it mag concern Be it known that I, ANDRE TI.'PA-L1\I-.:cUsH, a citizen of the Umted States, residing at Conrad, in the countyof Tetonand State of Montana, have invented certain new and usefulImprovements in Flax Harvesting 7 Attachments, of which thefollowing' isa specification. I.

This invention relates to improvements in harvesting machines andit-isthe principal object of the invention to-provide an attachmenttherefor for harvesting fl axg whereby the flax will have its rootsremoved from the soil during the harvesting operation, thus obviatingconsiderable waste and effecting a material saving. upon part of a user.

Another and equally important object of r the invention is to provideaharvesting mahence, rendering the same interchangeable.

chine attachment which can be engaged or applied to any standard type ofmowing machine with but slight alteration thereto,

v It is a more specific object of the invention to provide a harvestlngmachine employing rotatable pulling elements between which the flax tobe harvested is passed. In order that the invention and the man-.

ner of its application may be readily understood by those skilled'in theart, I have in the accompanying illustrative drawings and in thedetailed following description based thereon set forth a preferredembodi ment of the invention. j

In the drawings: v

' Figural is a fragmentary top plan of the improved flax harvestingattachment,

Fig. 2 is a vertical longitudinal section tl1eret-hrough,and V Fig. 3.1s a vertical transverse section through a portion of thc'same.

aving more particular reference toithe drawings, in connection withwhich like re'f- 4 erence characters will designate correspond ing partsthroughout the several views, F

represents the frame of the standard type of mowing machine, the sicklebar and guards thereof being removed and 0 represents the usual form ofendless conveyor movable thereacross and having its'opposite endssupported on suitable rollers'or pulleys.

their opposite endswconnectedby tran'sversely disposed elements andtheir inter-V versely. disposed arms generally indicated by thenumeral2. -The rear portion of the frame 1 is boltedor otherwise securedto V the adjacent portion of the mowingmachine frame F and in this way,obviously, will be cari 'iedtherewith during the movement of the mowlngmachine over a field. 1

V Extendinglongitudinally oftheframel and supported in suitable bearingsarranged lnthe opposlte ends thereof is a driven shaft 3 carrying asprocket wheel 4-011 its outer end, which sprocket wheel receives asuitable chain thereabout having connection withthe bull wheel or driveof the mow ing machine. A second sprocket wheel 5 is also mounted on thedriven shaft 3 ad jacent the wheel 4 and receives a chain 6 thereabout,said chain extending forwardly into engagement with a sprocket wheel 7car- .ried-upon one end of a countershaft 8 sup-" ported in bearingsarranged upon the forward portion of the frame .1 as 'at.9 and arrangedin a. tubular casing 10.

A plu'rality'of tapered rollers 11 are provided' and are formedwith'trunnions and are rotatably mounted upon the forward portion of theframe 1 in juxtaposed relat on, portions of said rollers being coatedwith" rubber 12 or a similar composition whereby thenfiax passmgbetweenthe; same trunnions'at the inner'or rear ends of the engaged withpointed deflecting elements 18 V provided in turnwith sockets inwhichare journaled'. the forwardtrunnions of the ad- 7 acent rollers asshown at 19'. Truss rods 20 v are connected to the-upper sides of thevari- The and carry 5 ous deflectors l8 and extend rearwardly intoengagement with the front portion of the frame 1 whereat they areprovided with locking nuts 21 to'preventthe displacement of the same. Inthis way, it will be readily understood that the rollers '11 will beafforded a substantial rigid support and as a consequence will beprevented from moving unduly with relation to the surface ofthe fieldover which they are passing.

In operation, the mowing machine to which the attachment is applied isof course moved over a field having the flax planted therein; thetapered rollers 11 directing the flax therebetween and pulling the samewhen t IS engaged with the coated portions 12 thereof, whereupon thesame is then directed 'onto the endless conveyer belt by means of theordinary form of feeder, not shown.

From the foregoing, it is to be noted that the fiax harvested with myimproved attachment will be pulled from the soil with the roots thereofintact, thus, effecting a. material saving upon part of a user.

Manifestly, the construction shown is capable of considerablemodification and such modification as is within the scope of my claim, Iconsider within the spiritof my invention.

runners secured at the forward ends to the deflectors and at their rearends to the frame, and truss rods having their forward ends eonnectedtothe deflectors and their rear-ends secured to the frame.
